Electronic GK Questions

World Environment Day is celebrated on June 5 every year to remind people to save nature and the earth by stopping their non-environmentally friendly activities. Let's know more about this day, its history, significance, and theme.

A capacitor stores energy in the form of an electrostatic field between its plates. Increasing the size of the plates increases the capacitance because there is more room for the electrons to escape.

In a generator, a rotating magnetic field is used to produce electrical energy. When a conductor, such as a wire, moves through a magnetic field, a voltage is induced across the conductor. This is known as electromagnetic induction, and it is the fundamental principle behind how generators work.
